PLANING AND MATCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 330,564, dated November1'7, 1885.

Application filed July ai,'1ss4. Serial Nd. 139,315. (No model.)

To all whom it may concern:

Be it known that I, EDWARD H. N. CLARK- soN, of Baltimore city,Maryland, have invented certain new and useful Improvements in Machinesfor Making Flooring, of which the following isa specification, referencebeing had to the accompanying drawings, forming part hereof, in whichFigure 1 is a top plan View of front end of Fig. 2 is a similar view ofthe rear end of the machine, the rollers on the ex treme rear (as shownon left of Fig. 3) being omitted. Fig. 3 is a side elevation of the rearof the machine; and Fig. 4 is a vertical transverse section on line 0000, Fig. 3.

Like figures indicate the same parts in all figures of drawings.

My invention relates to machinery for manufacturing flooring; and itconsists in the construction, arrangement, and combination of parts,which will be fully described, and afterward specifically pointed. outin the claims, whereby a machine is furnished which will plane, rip, andtongue and groove three pieces of flooring out of a single board fed inat the front of the machine.

Referring to the drawings by figures; 1 is the bed of the forward partof the machine, upon which is mounted a roll, 2, a planer- 0 head, 3,driven by belts on suitable pulleys,

4, a pair of cutter-heads, 5 and 6, a second roller, 7, a pair ofrip-saws, 8, driven by belts over pulley 9, and a pair of separators,10.

The construction and operation of these devices will be well understoodby persons skilled in the art, forming,as they do, a complete machinefor planing the top of a plank, tonguing one side and grooving theother, and ripping the plank into three pieces. Attached at the 0 rearof this bed are two guideways, 11, each having a flange, 12, whichguide-flanges recede outward from each other from front to rear of themachine, and are substantially continuations of the separators 10.

On the bed or the rear portion of the machine where these guideways endare mounted the following devices, viz: a frame, 13,

swinging on shaft 14 and carrying at its outer end a roller, 15, on oneside of the machine, and a frame, 16, mounted on shaft 17, carryingroller 18 on the other side of the machine, the shafts 19 and 20,onwhich the rollers 15 and 18 are mounted, lying ata slight angle toeach other, so as to be at the right angle to the guide-flanges 12;also, a shaft, 21, carryi'ng central roller, 22, at a right angle to thecentral line of the machine; also, a groovlng cutter-head, 23, and atonguing cutter-head, 24, mounted on adjustable plates 25 and 26. Thesaws 8 are mounted on frame 27, which are also adjustable toward andfrom the center of the machine. The front end of the guideways 11 and 12are adj ustably fixed to the bed 28, on which the saws and frames aremounted, so that they may be set with relation to the saw as desired,but are intended after being set to be adjusted simultaneously with thesaw. The adjustment of the parts is made simultaneous by means of screwsswiveled through the frame of the machine and engaging the movableparts, one of such screws being shown in Fig. 3, and two others, 30 and31, being shown in Fig. 1. These screws are threaded into the movableportion, and are each provided with bevel-gear,which engages a similarbevel-gear on a longitudinal shaft, 32, as shown in Figs. 1, 3, and 4.

In Fig. 4 the manner of mounting these adjustable screws is shown, 33being the bevelgear on screw 29, 34 the corresponding bevelgear on shaft32, and 35 a block or bearing through which the screw swivels, thethread of which engages a nut attached securely to the frame whichcarries the cutting-head 24. The plank which it is desired to convertinto three pieces of flooring is fed under the roller 2 and planer-head3, which planes its upper edge. It now passes between the cutter-heads 5and 6, the first of which grooves one edge, while the latter tongues theother. It passes onward under the roll 7, is ripped into three pieces bysaws 8, (whose forward edges are slightly closer together than the rearedges,) which pieces are separated by separators 10, and furthers themapart by the beveled front edges of the guide-flanges 12. At about thetime the rear end of the plank is leaving the roll 7 the front ends ofthe three pieces have at 38, 39, and 40. The left-hand edges of 38 andthe right-hand edge of 40 are the outer edges, respectively, of theoriginal plank, and are respectively tongued and grooved. The inner edgeof the piece 38 is grooved by the action of the outside of thecutter-head 24. The inner edge of the piece 40 is tongued in a similarmanner by the outer edge of the cutter-head 23. The central piece, 39,passes between cutter-heads 24. and 23, and is grooved and'tongued bythem in the order named.. This completely finishes the three pieces offlooring, leaving them dressed, tongued, and grooved without thenecessity of any handling after the original plank is put into themachine.

Having thus described my invention, what I claim is- 1. A machine formaking flooring, embracing the following mechanisms, consecutivelyarranged in the order in which they are enumerated, viz: planing-knives,heads mounted on each side of the passage-way to tongue or groove theouter sides of a board, saws to rip the board longitudinally, separatorslocated in line with the saws to enter the kerfs and laterally separatethe pieces into which the board has'been ripped, and heads arranged andlocated at or beyondthe ends of the separators, whereby the inner edgesof the separate pieces are tongued or grooved, parts being combined asand for the purpose set forth.

2. In a machine for making flooring, the combination of planing-kniveslocated centrally in the path of a board, heads located at the sides ofthe board to tongue or groove its outer edges, and saws located in thepath of the board to rip it longitudinally, as set forth.

3. In a machine for making flooring, the combination of planing-knives,heads located on the sides of the machine for tonguing or grooving thesides of the board, a saw located in the path of the board to rip itlongitudinally, a separator located in the line of the saw-kerf toseparate the pieces ripped apart by the saw, and a head located beyondandin line with the separator to tongue or groove the two inner sides ofthe separated pieces, as set forth.

4. In a machine for making flooring, the combination of heads located atthe sides of the machine for tonguing or grooving the sides ofa board,saws located in the path of the board to rip it as it is propelledforward, separators in line with the saws to laterally part the ribbedpieces, heads located in line with the saws, and separators to tongue orgroove at the sides of the machine for tonguing or grooving the sides ofa board as it is fed forward, saws located in the path of the board torip it longitudinally, and a separator located in line with and beyondeach saw to enter the kerf and laterally part the ripped pieces, wherebytheir intermediate adjacent edges are brought into position to beoperated upon, as set forth.

7. In a machine for making flooring, the combination, with mechanism forpropelling the stock through the machine, of heads for tonguing orgrooving the sides of aboard, saws for ripping the board into two ormore pieces, and a separator for laterally parting thc ripped pieces,whereby their intermediate adjacent edges are brought into position tobe simultaneously operated upon, as set forth.

8. In a machine for making flooring, the combination, with mechanism forpropelling the board through the machine, of saws for ripping the board,separators for laterally parting the pieces, and heads for tonguing orgrooving the edges of the ripped pieces, as set forth.

9. In combination, the saws 8, guide-flange 12, inclined and beveled, asdescribed, the feed-rolls 15 and 18, set at a slight angle, and thefeed-roll 22, set at right angles to the line of feed, as set forth.

10. In combination, the mechanism, the cutter-heads 5 and 6, saws 8,guides 12, cutter-heads 23 and 24, and suitable mechanism, substantiallyas described, whereby all the mechanism on one side of the machine maybe adjusted toward and from that of the other side, as set forth.

11. In combination, the inclined guideflanges 12, the separators 10, andthe saws 8, the forward edges of said saws being slightly nearer to eachother, as and for the purpose set forth.

12. In combination, the series consisting of cutter-heads, saw, andguide-flange on one side of the machine, the similar series on theopposite side, the adjusting-screws 29, 30, and 31, and thelongitudinalshaft 32, substantially as described.

In testimony whereof I have hereunto set my hand in the presence ofsubscribing witnesses.
